The morphology and magnetic properties of bulk crystalline and ball - milled Ho(Ni0.8Co0.2)(3) intermetallic compounds were studied. The influence of the duration of the high energy ball - milling (HEBM) for the final size of particles and crystallites was confirmed by a variety of complementary measurement methods. The crystallization of all studied specimens in the PuNi3 type of crystal structure was confirmed. The presence of an amorphous phase was evidenced at the final stage of pulverization. The influence of different grinding times is reflected in the variation of morphology and magnetism of as-milled powders. An emergence of nanoflakes having nanoflower-like morphology was found at the end of HEBM process. Furthermore, a slight variation of magnetic parameter was observed. Potential coating of the nanoflakes by Ni/Co oxides was demonstrated by XPS investigations.
